Don't go that way, because I could ask you to prove that your diagrams work in the reality.
Anyway, at least for me to be able to discuss about the light thing, I would need to know what is the exact form of the light curving, I don't know the mathematical name, but you know, the "angle" of the curve, how much is it? 'Cause I assume it is a constant, and I've observed that "bendy light" is an excuse for everything, maybe knowing the exact form of the curve, we could get something.
